Your doctor has requested a CT-guided bone biopsy. The CT scanner uses X-rays and advanced computer programs to create detailed images inside your body. This is a minimally invasive procedure that can usually be done without an overnight stay in the hospital. During a biopsy, one of our physicians will use images generated by a CT scanner (also called a cat scan) to accurately insert a needle into the suspect bone, allowing a sample to be removed for testing. Our team of expert musculoskeletal physicians, nurses and technologists is led by Thomas J. Learch, MD, chief of Musculoskeletal Radiology.
